The independent bits of Hungary in the middle of the Hapsburg domains and the thin line of provinces stretching up to the Baltic. It looks like random conquest rather than random inheritance and defies the neat borders that a lot of players seek out.

It's one of the most fun games... but you will be invaded by The Mamluks and at least one of the Ottomans, the Eretnids, Ak Koyunlu, Chobanids or Jalayirids on day one. All but the Ottomans are tribal, so you can just accept vassalization and wait for an eventual succession crisis.

But you have to act extremely quickly when you do finally get an opportunity to expand.
